He's been offered support from his fans since using social media to highlight his mental health.

But former X Factor contestant Jahmene Douglas has sparked fresh concern after posting a rather worrying tweet that referenced the devil and suicidal thoughts.

He took to Twitter on Friday evening where she shared a message that said: "For any of you struggling with suicide out there. Here's my perspective; I hope this helps distinguish the devil's thoughts from your own."

He'd attached an image to the message, which seemed to be therapy-inspired guidance for those struggling.

The post quickly garnered more than thirty re-tweets and over 150 likes, plus a flurry of supportive comments.

Poignantly, one fan wrote: "The suicide rate for young men is tragic-so well done 4 being brave enough 2 say how you feel," while another chimed in: "I hope you got the support from friends and family and we are all here if you ever need to offload."

The latest online activity comes just days after Jahmene first detailed his issues.

"My mind is plagued with suicidal thoughts whenever my defences are down," he wrote in a Twitter post on March 3rd, titled This Is Me.

He continued: "I feel so broken, lost and worthless. It doesn't seem to matter how much I try to fix myself, who I talk to or what I put in place it always comes back to this."

Fellow celebrities and followers alike soon inundated him with messages of support and love.

Returning to the social media site a few days later, he said the note "wasn't intended as a goodbye, but simply me slipping a note under the prison door to see if anybody knew of an escape".

Alongside a new message that was titled Sorry, he wrote: "Unfortunately the devil still found a way in, but over the past few days I've been kicking him out. I find walking helps, so I walked and walked until my feet hurt."

Jahmene, who came runner-up to James Arthur in 2012, said he thinks of himself as an optimistic person and doesn't believe he suffers from depression, but his troubled upbringing has led to an ongoing battle with his mental health.

He continued: "I was born into abuse so my complete foundations are crumbling bricks. I feel as though I've lost my identity - the grasp of that which defines me."

Jahmene said he will focus on his music "as it's the only thing that gives me purpose".
